  • The valve would fail catastrophically and basically siphon oil into the engine. It’s a questionably complicated German design of course. It was particularly vulnerable to freezing, which happens if the engine wasn’t run long enough to boil off all condensation.

    It got close for me once. The only time it left me stranded. Stopped at a light. Pulled away. Bam, thick black smoke and the engine stalled. I’d replaced it about 45000 km before and most trips were 70km but I guess it was too much.

    I ran my mk3 golf without coolant for a summer. I abused that poor thing so much.

    That’s your problem, they’re designed for people who want to waste time on their lawn and drink a beer. People who want to get it done with have zero turn mowers.

    Sodium silicate in the oil. Bleach in the gas. An iron spike driven into the ground just below the height of the grass.

    But really the best way to deal with it is to get over it. I know sometimes it’s hard to get over an irritating sound, but it helps your mental health if you don’t get angry about something minor and entirely outside your control









  • If you don’t live in a hot climate, many heat pump water heaters take heat from indoor air. Be aware of that - you’re heating air, then moving that heat into the water tank. It really drops efficiency. But they’re almost certainly a lot cheaper to run long term than paying for oil deliveries! They’re not necessarily cheaper than gas, because gas is just so cheap. I’d be wary of replacing a working system, because it’s probably not going to break even, but check for incentives that might help with the cost.

    If you make the investment, a water softener could be a good investment. Draining/flushing and maintaining the anode rod is a big factor in longevity.

    Tankless is ok, but it burns oil or you need pretty serious electric service. One downside is that the hot water piping doesn’t get the heat transfer from the tank of hot water so the whole pipe length cools fairly rapidly; 1hr between showers and you need to run the tap for a while.

    I believe that a heat pump boiler should have backup electric heating elements that kick in when there’s high demand or if it is too cold for the heat pump to keep up.
